A school building upgrade with attached canopy involved installation of overhead glazing to allow natural light to get into the building, while providing a covered accessway for students and teachers.

The Spectrum 22 Series glazing bars were used over existing timber rafters. The sill extrusion used at the head along with a flashing ensured a watertight connection at the top of the glazing. The bottom edge of the glass was left free for water to drain off.

The 22 series glazing bars, along with other glazing bar series are excellent for curving to create domes, vaults and other curved architectural shaped structures.

Other glazing bar options include the 43 Series which allows for longer spans than the 22 series. The 100/102 Series is ideal for commercial applications. It boasts superior features which allow for purlins at glass joints on long runs and has integrated drainage channels to allow natural flow away of internal moisture such as condensation. The 100 Series glazing bar is compatible with 50mm wide rafters making it suitable to be used with timber, aluminium and steel rafters.
